    By on October 15, 2010 | Comments Off  Comments


    KantIsDead writes “MIT’s Technology Review adds to the ongoing discussion of China’s monopoly on rare earth metals, an issue that was temporarily catapulted to national attention during China’s rare earth embargo of Japan. The current article focuses on the search for alternatives to rare earth metals that would undercut China’s monopoly and allow nations to develop their industry without fearing the hand of a Chinese embargo.

    kaulike writes “The European Space Agency’s GOCE satellite, launched in March 2009, has provided a spectacular, highly detailed map of our favorite gravity well. This map shows the normalized surface of the earth as defined by gravity, showing the relative altitude differences from the average for each surveyed point. The article provides the helpful metaphor that a ball resting on this surface would not roll anywhere, even though there would be visual (more…)

    elyons sends word out of UCLA of a completely unexpected discovery in the physics of the Sun-Earth interaction — a previously unknown basic mode of energy transfer from the solar wind to the Earth’s magnetosphere. “‘It’s like something else is heating the atmosphere besides the sun. This discovery is like finding it got hotter when the sun went down,’ said Larry Lyons, UCLA professor of atmospheric and oceanic sciences. ‘We all have thought (more…)

  • ELF Knocks Down AM Towers To Save Earth, Intercoms

    ScentCone writes “The ELF (Earth Liberation Front) has claimed responsibility for destroying the primary AM towers used by radio station KRKO in Washington state. From their statement: ‘AM radio waves cause adverse health effects including a higher rate of cancer, harm to wildlife, and that the signals have been interfering with home phone and intercom lines.’ The poor intercom performance must have been the last straw.”
